Daily testing will be available this week in the town for anyone experiencing symptoms of coronavirus.
NHS Dumfries and Galloway interim director of public health Valerie White said: “Additional covid testing has now been secured for the region, and is being deployed to Stranraer.
“This is in recognition that although new cases of covid within Wigtownshire have decreased quite markedly in recent days, rates within the area still remain high.
“We are in continual discussions with our partners nationally around securing additional testing capacity, and are pleased we can now supplement what was in place.”
The area’s test sites are at Ashwood House in the town and at the Riverside car park in Newton Stewart.
